Application May 7, 1958, Serial No. 733,547

2 Claims. (Cl. 5-201).

This invention relates to bed frames, and more particularly to fnames having longitudinal side rails detachably secured to transverse end rails and arranged to sup port the weight of the bed.

The present invention contemplates a bed frame construction which may be used forsupporting a box spring and mattress, either with or without a headboard, to provide a Hollywood type bed, or which may be used to support an entireconventional bed. In'the latter case, the frame serves to stiffen the bed structure and permits moving of the bed without damage to the bed or the floor.

The bed frame includes a unique corner construction for releasably joining the side rails to the end vrails. This construction combines great inherent strength and rigidity with easy manipulation in mounting and dismounting. The parts cooperate to hold the corner rigid against racking and twisting forces when engaged, but may be disengaged by simply lifting the side rails from the end rails.

It is a principal object of the invention to provide a bed frame which may be easily and simply set up and taken down, but which is sturdy and rigid when in use.

Another object of the present invention is the provision of a bed frame construction which may be adapted for supporting a box spring arid mattress, or for supporting an entire conventional bed.

A further object of the invention is the provision of a corner construction for a bed frame which is securely locked together by the weight of the parts, but which may be quickly released by lifting the side rails straight up from the end rails.

Other objects and features of advantage will become apparent from the consideration of the ensuing description and, accordingly, it is not wished to limit the scope of the application to the embodiments shown in the drawings, except as defined in the appended claims.

In the drawings:

Figure l is a perspective view of a corner portion of one form of bed frame constructed in accordance with the present invention.

Figure 2 is a plan sectional view taken substantially on the plane of line 22 of Figure 1.

Figure 3 is a cross sectional view of a size adjusting clamp in operative position on a side rail of the frame of Figure 1. I

The bedframe of the present invention comprises primarily a pair of end rails 12 adapted to be supported on the floor, and a pair of side rails 14 which are supported on the end rails. The rails 12 run transversely beneath the ends of the bed while the rails 14 run longitudinally of the bed, the whole forming a rectangle. The rails are releasably secured in such configuration by means generally indicated at 16 provided at each corner of the bed. For purposes of illustration, the drawings show only one corner of the bed. However, it will be understood that all four corners are similar in ice for all.

The means 16 includes an upstanding flange 18 on the end rail 12 and a downwardly depending flange 20 on the side rail 14, 7 These flanges are positioned at the opposite ends of the end and side rails and confront each other when brought into alignment. A slot 22 is formed in the lower half of the depending flange 20 and a corresponding slot 24 is formed in the upper half of the upstanding flange 18. When these slots are brought into registry, by holding the side rails in correct position above the end rails, the side rail may be lowered so that the portion of the flange adjacent to the slot will be engaged in the slot in the confronting flange. This interfitting slot construction provides a firm and rigid joint which can be disassembled merely by lifting the side rail from the end rail.

Additional rigidity is imparted to the corner by the provision of a member 26 secured to and extending from one of the'rails 12 or 14 so as to present a shoulder portion 28 against which the otherrail will hear when the slots 22 and 24 are engaged Thisshoulder 28 is spaced from the slots and reinforces theassembly against a scissoringmovement of the rails.

Preferably, for reasons of strength and durability, the side and end rails 14 and 12 are formed of angle iron members. The end rails may be orientated with one flange extending upwardly, as shown in the drawings, to provide the flange 18, and the bottom flange may be used to mount casters 30 upon which the frame and bed may be moved freely from place to place. These casters 30 are preferably mounted somewhat inwardly of the ends of the end rails 12 so as to be hidden from view and to prevent entanglement with the bed covers.

The form of the invention illustrated in Figures 1-3 of the drawings is particularly suited for use in supporting an entire conventional bed. The frame serves to stiffen the bedstead and the casters permit moving of the bed without being impeded by the rug.

As here shown, an angle iron section is secured to the end of the end rail 12, this section providing the aforementioned member 26 which is formed with a flange welded in coplanar relation to flange 18 to provide the shoulder 28' against which rail 14 abuts, see Figure 2. The section is orientated so that one flange 32 has its outer face coplanar with the end of the rail 12. Formed in this flange 32 is a vertical slot 34 in which rides a bolt 36 secured to a bracket member 38. A nut 40 is threaded onbolt 36 and serves to clamp the bracket 38 at any desired height above the end rails 12. The bracket 38 includes a plate 39 to which the bolt 36 is secured. The plate extends downwardly from a vertical edge of the said bracket 38. The bracket 38 has a lower horizontal flange 42 which serves as a shelf upon which the wooden side rail 44 of the conventional wooden bedstead may be supported. It is noted that, when conventional finger and slot-type rails 44 are used, supporting of the side rails would tend to cause the headboard or footboard 45 to fall off the downwardly bent fingers. Therefore, a small metal strap 46 should be mounted by means of a screw 48 above the slot to prevent the headboard or footboard 45 from falling off the side rails.

Conveniently, in this form of the bed frame, the side rails 14 may be mounted directly on the end rails 12 with one flange of the side rail providing the depending flange 20. This is because the side rails bear no load directly but merely serve to position and stiffen the bed frame.

The invention described may be made adaptable to beds of varying longitudinal and transverse dimensions. The structure for accomplishing this is shown in Figures 1 and 3 of the drawings wherein the end rails 12 1 3 and side rails 14 are provided in two sections, nesting one within the other, which are secured together by a clamp 64. The sections of the rails may be telescoped to the desired dimension and a thnmbscrew 66 on the clamp tightened to lock the-rail sections together.

From the foregoing it will be apparent that the bed frame construction of the present invention provides a structure well suited for use with either conventional or Hollywood type beds, the structure being easy to assemble and take apart with a simple upward lifting movement while providing great strength and rigidity when assembled.

I claim:

1. An auxiliary unit for supporting a bed frame comprising: a pair of angle-iron end rails, each of said end rails beingso oriented that the longitudinal flanges thereof extend upwardly therefrom, each of said flanges hav ing slots at either end thereof; a pair of angle-iron side rails supported on said end rails whereby to form a rectangular unit somewhat smaller than the bed frame to be supported, each of said side rails being so oriented that each has a longitudinal flange extending downwardly therefrom, each of the said flanges having slots at either end thereof, each of the slots in the said side rails being of suitable width and depth to register with and securely interlock with a slot of one of said end rails whereby the confronting flanges of the said angle-iron rails may be locked together; an upright member fixedly secured to each end of each of said angle-iron end rails, each upright member beinggspaced a distance equivalent to the width of a side rail from the nearest slot in the flange of said angle-iron end rail, the said member serv ing when the said unit is assembled to abut against the outside edge of a side rail while the said side rail is interlocked with an end r'ailby means of said slots; and means on each upright member for attaching said member to a bed frame whereby to support said bed frame at all four corners thereof,

2. The structure of claim 1 wherein each upright support member has a bracket formed of a piece of angleiron mounted thereon for the support of the said bed frame, the position of the said bracket on the said member being vertically adjustable.
